Title: Bidirectional parallel printer interface
Inventor: BECK JAMES L
IPC: G06F3/12
Filed: 1992-02-13
Abstract: PURPOSE: To make an operator confirm the state of a printer without going to the place of the printer by making a data processor report whether information transmitted to the printer is data signals or state signals. CONSTITUTION: A computer 40 which is the data processor is connected to the printer 41 by a cable 42. When the power of the computer 40 and the printer 41 is turned ON, it is assumed that they are operated in a mode where the printer 41 is placed in a single direction. In order to activate a bidirectional mode so as to make the printer 41 able to transmit and receive the information, the computer 41 sets-INIT to low and the printer 41 sets +BUSY to high in response to it. When the printer 41 is prepared to receive a state command, +BUSY is turned low. In the case that the printer 41 does not set +BUSY, it is assumed that the computer 40 can not respond whether the printer 41 is unidiretional or bidirectional due to the fault of a hardware.

Title: Method and apparatus for producing polycrystalline thin film and production of oxide superconductor having polycrystalline thin film
Inventor: IIJIMA YASUHIRO
IPC: H01L39/24
Filed: 1993-03-19
Abstract: PURPOSE:To provide a polycrystalline thin film having excellent crystal orientability, an apparatus for production of this thin film and an oxide superconductor having the polycrystalline thin film. CONSTITUTION:The particles generated from a target 12 are successively deposited on the surface of a base material during movement and the surface of this base material is irradiated with anion beam at the irradiation angle of a prescribed range from a direction diagonal with this surface during the particle deposition in the method for successively forming the polycrystalline thin films by a film forming method on the surface of the long-sized base material A while moving the base material. On the other hand, the region to be irradiated with the ion beam off the irradiation angle of the prescribed range is provided with shielding members 5a, 5b to prohibit the deposition of the particles in this region. As a result, the thin films are formed by covering the region exclusive of the range where the irradiation angle of the laser beam is specified with the shielding members and, therefore, the deposition of the atoms in a way as to orientability inferior does not arise any more.

Title: Projection image displayer
Inventor: SUZUKI ARINOBU
IPC: H01J31/10
Filed: 1979-05-16
Abstract: PURPOSE:To obtain projection images of a high definition by letting the focusing face of image formed on a fluorescent screen coincide with the curved surface of projection screen. CONSTITUTION:The difference d between the curved surface of a projection screen and the focus of picture light is obtained at each point on the projection screen and the points on a fluorescent screen, corresponding to the points on the projection screen, are made uneven as much as d'=d/M2 (where M is the scale factor of projection), larger than the spherical surface R. In short, when d>O, the focus of picture light is on cathode-ray tube rather than the projection screen and the fluorescent screen structure becomes convex. Also, when d<O, the focus point of the picture light is located at a position on the opposite side of the cathode-ray tube begond the projection screen and therefore the fluorescent screen structure becomes concave.

Title: Signal selection circuit
Inventor: OGAMI CHOJI
IPC: H03K17/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a signal selection circuit from which a whisker-like pulse being a pulse with a narrow width is not outputted as a signal after switching in the case of switching an input signal. SOLUTION: A selector 124 is a conventional changeover means that selects and outputs either of two systems of input signals 111, 112 depending on a change in the polarity of a switching signal 118. An output signal 131 of the selector 124 is given to a data input terminal of a latch type flip-flop circuit 132. The polarity of the switching signal 118 is inverted by a 2nd inverter gate, delayed at a delay circuit 136 by a prescribed time and the resulting signal is ORed with the switching signal 118 and its logic output 138 is given to a latch signal input of the flip-flop circuit 132. A signal 139 that results from replacing a pulse with a narrow width outputted at the signal switching of the selector 124 with a just preceding signal is outputted as a signal after the switching from an output terminal of the flip-flop circuit 132 and production of a 'whisker-like' pulse is prevented.
